SYSTEM AND METHOD FOR ATTACHING ARCHITECTURAL
MOLDINGS AND INSULATION SHEETS TO BUILDINGS
Description
This invention relates to a system for attaching architectural molding or
insulation sheets to buildings, and more particularly to attaching
architectural moldings
formed from a light foam plastic core covered with a hard base coat or
insulation sheets
of light foam plastic to an exterior substrate or wall of a building or
structure using
fasteners that bear against an insert or strip that extends through the
moldings or sheets.
BACKGROUND OF THE INVENTION
Within the last few years, the use of light-weight prefabricated architectural
moldings or shapes for application to the exterior walls of buildings has
increased. Such
moldings are used to enhance the aesthetic beauty of a surface area. These
moldings are
constructed of a light-weight plastic material covered by a hard protective
base coat. A
finish coat also is usually applied over the base coat once they are attached
to a wall or
substrate of the building structures.
Heretofore, in order to secure the molding to the structures, the shapes were
adhesively attached to the substrates or walls of the structures. However,
moisture often
accumulated between the moldings and the substrate, thereby eroding the
adhesive and
causing separation of the molding from the substrate. Where it would be
desired to


CA 02271496 1999-OS-10
3
apply the molding to a wall of a building covered with a moisture barrier type
plastic
sheeting, various fasteners thus were employed.
One type of fastener is a nail or screw with a large plastic washer. The large
plastic washer is designed to be pressed into the molding until it is at least
slightly below
the surface so the opening created in the base coat can be filled, thereby
creating a
generally flat outer surface. However, the large size of the washers and the
hardness of
the coating on the moldings often caused the coating to crack, thereby
requiring repair or
replacement. Furthermore, because of the large area necessary to be recoated
due to the
size and effect of the washer, variations in shading sometimes were present on
the
moldings after the finish coat was applied.
It has also been known to use adhesives or washers and screws, separately or
in
combination, to attach insulation sheets to buildings. Installing insulation
sheets, which
usually are 2 feet by 4 feet sheets, with such fastening systems often led to
the same or
similar problems as encountered in the mounting of moldings as above
mentioned.
1 S SUMMARY OF THE INVENTION
The present invention overcomes the problems in securing architectural molding
to substrates on structures or insulation sheets to buildings. The molding of
the present
invention includes a core of light plastic material covered by a skin of hard,
preferably
cementitious, material. A fastening strip of substantially rigid material is
embedded
within the core of light plastic material. To mount the molding onto the
substrate of the
structure, the molding is placed against the structure in the desired
location. Then,
fasteners, such as drywall screws, are inserted completely through the hard
skin or base
coat into the core and through the strip in the core of the molding and into
the substrate
of the structure until the heads of the screws abut and press against the
strip. If desired,
prior to fastening, a small hole formed through the skin and into the core can
be made by
a drill or other device for facilitating the use of fasteners.
The use of fasteners such as screws allows the molding to be securely attached
to
the substrate of the structures. Furthermore, using fasteners with pointed
ends allows for
the screw to penetrate the hard base coat or skin and the molding by forming a
small hole
in the skin and core to the strip and without causing appreciable damage to
the base coat
or molding. Thereafter, the small holes can be filled very easily with a
suitable material.


CA 02271496 2004-06-08
4
Similarly, insulation sheets of the present invention include at least one
fastening strip
of substantially rigid material embedded within the sheet. The sheets are then
mounted onto
a building by inserting fasteners through the sheets and strip and into the
building. The strips
may be sized and arranged to interlock adjacent sheets.
Another aspect of the invention provides a method for attaching a unit of
construction
material adapted to engage a building, wherein the unit includes a body of
light-weight plastic
having a plurality of sides, a back wall, and a top wall. The method
comprises: embedding
an elongated strip of rigid material entirely in the body, mounting the unit
on the building
such that the back wall of the unit directly contacts an exterior or interior
surface of the
building, and applying fasteners having heads and shanks through the body and
strip of rigid
material and in engagement with the building and where the heads of the
fasteners contact and
bear against the strip and the shanks extend first through the body, then the
strip and into the
building thereby attaching the unit to the building.
Accordingly, the present invention seeks to provide architectural molding and
insulation sheets that may be easily and securely attached to substrates of
structures and/or
buildings.
Further, the invention seeks to provide for attaching architectural molding
without
causing appreciable damage to the base coat or skin of the molding or the
molding itself.
Still further, the invention seeks to provide for attaching insulation sheets
without
causing appreciable damage to the sheets.
her aspects, features and advantages of the invention will be apparent from
the
following detailed disclosure, taken in conjunction with the accompanying
sheet of drawings,

DESCRIPTION OF THE INVENTION
Referring now to the drawings, Figs. 1 to 4 show one design shape for the
architectural molding of the present invention, generally indicated by the
numeral 10.
The molding 10 includes a core of light-weight plastic material 12 with a slot
or channel
5 20, a reinforcing mesh 14, and a base coat 16. The plastic material 12 is
preferably any
suitable foam plastic (sometimes called cellular plastic) having light-weight
and good
strength characteristics, such as foam polystyrene or Styrofoam plastic having
a desired
rigidity, but may be any other type of suitable light-weight plastic material.
Styrofoam is
a trademark of Dow Chemical Co., and constitutes an expanded cellular
polystyrene.
The desired shape of the plastic material 20 may be prefabricated or it may be
formed by
cutting the shape from a foam plastic block. A mesh 14 is located on top of
the desired
shape of the plastic material 12 to reinforce the base coat 16. Preferably,
the mesh 14 is
a 4.5 ounce standard fiberglass woven mesh. The base coat 16 which is applied
over and
to embed the mesh 14 is comprised of a suitable cementitious material, such as
a
hydraulic cement, which when cured forms a hard outer surface for the molding
to
protect the molding 10 from outside elements, for example, moisture, and which
may
receive any suitable finish coat.
As shown in Figs. 1 to 3, a slot or channel 20 is formed inside the core of
the
plastic material 12. The slot 20 may be formed by moving an L-shaped hot wire
through
the plastic material 12 before applying the base coat 16, or it may be formed
by any
other suitable means, such as molding or cutting. A hot wire (not shown)
passed through
the length of the molding 10 forms an L-shaped channel or slot 20 in the
molding 10.
The mesh 14 and base coat 16 may then be applied over the plastic material 12
to seal off
the top end of the slot 20.
Once the slot 20 is formed, a strip of rigid material 22 is then inserted into
the
slot 20. The size of the slot may be such that the strip may be easily
inserted. The strip
22 is preferably a polyurethane, or polycarbonate resinous material such as
that marketed
under the trademark Lexan, but may be made of any suitably rigid material,
such as
wood, metal or other plastic. Lexan is a trademark owned by General Electric
Corporation.
In application, the molding 10 is placed into its desired location against a
suitable
substrate or wall. While the molding 10 in Fig. 4 is shown placed on the
exterior wall


CA 02271496 1999-OS-10
6
of a building around a window 50, it should be appreciated that the molding 10
may be
used in numerous places, including around doors, on columns or facia, both
exteriorly
and interiorly. The molding 10 may be initially held in its desired place by
hand or other
means, such as an adhesive. Once the molding 10 is in its desired place, a
plurality of
fasteners, such as drywall screws 34 are inserted into the molding 10. Such
screws
generally include a beveled head and a threaded shank. In terms of a screw 34,
the
screw is placed on the molding in alignment with the strip 22 such that it
will pass
through the strip 22 and into the substrate of the structure 32. In order to
facilitate the
proper placement and positioning of the screw before it is driven through the
molding, a
line or other suitable marking or indicia may be used on the top of the base
coat 16 of the
molding 10 such as a dashed line 23 shown in Fig. 1. The screw 34 may be
inserted
until the beveled head of the screw 34 contacts and bears tightly against the
strip 22 in
the core of the plastic material 12. The molding 10 will then be securely
fastened to the
substrate of the structure 32.
1 S Although the length of the strip 22 can vary, the strip preferably should
be sized
to extend substantially the full length of the molding. The strip should also
be of
sufficient width to allow for the fasteners 34 to have sufficient area to pass
through the
interior section of the strip 22 and also to define the appropriate bearing
contact with the
foam plastic core 12. It is also desired that the strip 22 has a sufficient
width to press
against a sufficiently broad part of the plastic core material 12 of the shape
or molding 10
when the fastener 34 contacts or bears against the strip 22 to prevent the
strip from
penetrating the core material or moving through the material, whereby the
molding 10
will be securely fastened to the substrate of the structure 32. For example,
it is known
that a strip 22 having a width of about one inch (2.54 cm) and a thickness of
about one-
eighth inch (3.5 mm) may be used on the molding 10 shown in Figs. 1 to 4
having a
width of about nine inches (22.86 cm).
As shown in Fig. 3 and Fig. 4, small holes 40 will be formed in the base coat
16
and the upper portion of the plastic material 12 where the screw 34 has
passed. The
holes 40 may be filled with cementitious material or other suitable material
such as
caulking, and smoothed as shown at 56 on the section of molding 10 on the left-
hand side
52 of the window 50 in Fig. 4. If desired, a finish coat may then be applied
over the
base coat 16, or over the holes 40 themselves, to form a uniform surface, as
shown at 58


CA 02271496 1999-OS-10
7
below the bottom part 54 of the window 50 in Fig. 4. A suitable finish coat is
preferably
an acrylic-based material with a stone aggregate, but may be any other
suitable type of
finish coat. The finish coat, which may be up to one-quarter inch thick, may
be applied
by spraying or troweling the material onto the base coat, and then allowed to
cure.
Another architectural design shape for a molding, generally indicated by the
numeral 60 is shown in Fig. 5. This embodiment also more clearly demonstrates
the
insertion of the strip 22 into the core of the molding 10. It should be
appreciated that
this invention may be used with any of the numerous shapes of architectural
moldings or
other designs such as desired on imitation stucco surfaces.
It should also be appreciated that the system of attaching a molded foam
plastic
trim piece to a structure may also be used without providing the trim piece
with an outer
hard base coating. Such a base coat of cementitious material, along with any
finish coat
or coats may be applied at the building site. The attaching system of the
present
invention is an improved system over the prior art systems identified in the
Background
of the Invention.
Referring now to Figs. 6 and 7, insulation sheets 70 or panels utilizing the
attaching system of the invention are shown. The insulation sheets 70 are
generally made
of a suitable foam plastic, such as Styrofoam plastic. The system includes the
formation
in each sheet 70 of a plurality of longitudinally extending slots or channels
72 and/or U-
shaped channels 74. The slots may be formed using a hot wire, or using any
other
suitable means, such as molding or cutting. The slots or channels 72 extend
longitudinally through the central area of a sheet, while U-shaped channels 74
forming
about one-half of a full channel may be formed on the edges of the sheets 70
so that a
complete slot may be formed where another sheet with a similar but opposing U-
shaped
channel 74 is placed on top of the edge of the sheet, as shown in Fig. 7.
Once the slot is formed, strips like those in Figs. 3 and 4 may be inserted
into
each of the slots 72 and the edge channels 74. The strips 80a, 80b and 80c may
also be
of such a length to extend entirely through one sheet and into one or more
adjacent sheets
of material. Thus, adjacent sheets may be interconnected or interlocked to one
another.
Furthermore, the channels 74 on the edges of the sheets 70 serve to receive a
fastening
strip 80a, 80b and 80c to interconnect or interlock the adjacent sheets
together along their
longitudinal edges.


CA 02271496 1999-OS-10
8
It should be appreciated that any number of channels may be provided in a
sheet,
and that the edge channels may be omitted. Further, the channels may extend
horizontally or vertically, but preferably parallel to an edge of the sheet.
To secure the insulation sheet 70 to a building, the sheet 70 is first placed
against
the building in its desired location. The sheet 70 may be held in place by
hand or by
other means, such as using adhesive. Once in place, a plurality of fasteners
such as
screws are inserted into the sheet 70 such that they will pass through the
strip 68 and into
the building. Lines or other marking or indicia means may be used to
facilitate the
proper placement of the screws. The screws are then driven into the substrate
or wall on
which the sheets are mounted until the screw heads engage and press against
the fastening
strips. The holes formed by the screws may be filled with a suitable material
if desired.
After the insulation sheets are secured to the wall, a mesh and coating are
generally
applied to the surface of the insulation sheets. As seen in Fig. 7, a
plurality of insulation
sheets or panels are mounted on a wall 78 to illustrate the interlocking of
adjacent sheets
and provide an interlocked layer of insulation. The sheets are generally
rectangular and
would normally be two feet by four feet in size and of any suitable thickness.
Sheets
70a, 70b and 70c are illustrated as being interlocked together by fastening
strips 80a, 80b
and 80c. Strips 80b and 80c extend through channels in sheets 70b and 70c to
interlock
and align sheets 70b and 70c. Strips 80b and 80c also extend beyond sheets 70b
and 70c
to provide an interlocking relation with other sheets that may be attached to
wall 78 in
adjacent relation thereto. Strip 80a fits in edge channels of sheets 70a and
70b to
interlock the edges of the vertically arranged sheets. While sheet 70a is
aligned with
sheet 70b, it could be appreciated they may be arranged in staggered relation.
From the foregoing, it can be appreciated that the invention provides an
improved
system of attaching foam plastic moldings or insulation sheets to walls or
substrates.
It will be understood that modifications and variations may be affected
without
departing from the scope of the novel concepts of the present invention, but
it is
understood that this application is to be limited only by the scope of the
appended claims.
